Activision may be heralded/hated as one of the world's biggest video game companies today, but in 1981, it was a much smaller company. A very different company, in a very different time.

Which is the only reason I can think of to explain this bizarrely wonderful promo video the company put together in 1981, which if you head to around 1:50 will show a rather ominous warning of the future.
